This study was undertaken to find the prevalence of high origin anterior tibial artery & its surgical significance. Sixty embalmed lower limbs belonging to 30 adult human cadavers form the material for this study. The origin of anterior tibial artery was observed by exposing popliteal artery in the popliteal fossa. The prevailing pattern, its branches and variations were observed,noted and photographed.High origin anterior tibial artery was seen in 2 out of 60 specimens , prevalence being 3.3%. The mode of bifurcation of popliteal artery was into an anterior tibial and posterior tibial artery at the upper border popliteus muscle.High origin anterior tibial artery & posterior tibial artery lying superficial to popliteus muscle is the most common type in high division of popliteal artery. Knowledge of the anatomical variations in the branching of the anterior tibial artery is important because damage to its branches can be limb or life-threatening in various knee procedures that involve extension of osteotomy to the posterior tibial cortex, particularly in high tibial osteotomy & total knee replacements.
